KENNEDY SPACE CENTER, FLA. - At the KSC Visitor Complex, actor and Master of Ceremonies Lance Henriksen (at podium) introduces four newly inducted Space Shuttle astronauts to the audience at their induction ceremony into the U.S. Astronaut Hall of Fame. From left center, they are Story Musgrave, Sally K. Ride, Daniel Brandenstein, and Robert "Hoot" Gibson. Also standing, left, is former astronaut James A. Lovell. Conceived by six of the Mercury Program astronauts, the U.S. Astronaut Hall of Fame opened in 1990 to provide a place where space travelers could be remembered for their participation and accomplishments in the U.S. space program. The four new inductees join 48 previously honored astronauts from the ranks of the Gemini, Apollo, Skylab, Apollo-Soyuz, and Space Shuttle programs.
